What happened?

After upgrading to webdriverIO 9, unable to take screenshot inside an iFrame using browser.saveScreenshot
I tried to use BiDi's "browsingContextCaptureScreenshot" but no matter what ever context ID i passed, it didn't work.

What is your expected behavior?

our application is wrapped inside an iframe, there is a workaround to use cdp to take screenshot, but sometimes getting target closed exception in after test.

How to reproduce the bug.

await browser.url('https://www.w3schools.com/html/html_iframe.asp');
await browser.pause(10000);//wait for it to load

    // // switch to a frame
    await browser.switchFrame($(`//iframe[@title='W3Schools HTML Tutorial']`));
    await browser.pause(3000);

    await $(`.w3-right.w3-btn`).click();

    await browser.pause(3000);

    await browser.saveScreenshot(`.testshot.png`);

Relevant log output

Error: WebDriver Bidi command "browsingContext.captureScreenshot" failed with error: unsupported operation - Non-top-level 'context' (4F8F8662A1A190C6542C420AD203A227) is currently not supported
